Serial No. 298,227.

My invention relates to chairs and couches, and more particularly to animprovement in resilient seats or bottoms for upholstered chairs andcouches. In general my purpose is to provide a resilient seat or bottomof sturdy construction which may be manufactured at a low cost and alsoinstalled with facility and dispatch in a chair or couch frame. Thus,the seat or bottom 9 is a separate transportableainit of predeterminedsize, which includes a series of coiled springs and a base of wovenmaterials adapted to be suspended at different elevations within a chairor couch frame by a set of expansible springs and a set of wire clipsnailed or screwed to the frame. As constructed the clips are adapted tobe secured in various Ways to the frame, thereby permitting theresilient seat or bottom to be installed very readily in chairs orcouches of different styles and kinds.

Thus the invention permits an upholsterer to either raise or lower aresilient seat or bottom within a chair or couch frame according todifferent upholstering needs, while affording at the same time anexceptionally secure attachment for the seator bottom within a chair orcouch, all as hereinafter fully described and more concisely pointed outin the claims.

In the drawings accompanying this application, Fig. 1 is a top view ofmy improved resilient seat or bottom attached to a wooden chair frame,and Fig. 2 is a sectional view thereof, Fig. 3 is a side elevation andsectional view, enlarged, of a portion of the resilient bottom andframe. Fig. 4 is.a perspective view of a portion of the seat frame withone wire clip attached thereto in an inverted position. Fig. 5 is aperspective view of a clip having two eyes to permit two suspensionsprings to be attached thereto substantially as delineated in Fig. 2.

The general practice in constructing chairs and couches is to provide anopen rectangular frame of wood or metal within and upon which aresilient seat or bottom is built by attaching strips of webbing to thebottom edges of the frame and then seating coiled springs upon thewebbing. The springs are tied together after they have 'been placedwithin the wooden frame, from beginning to end involves constanthandling of the chair or couch frame. My present conception is toproduce a separate resilient seat or bottom made of a flexible base 2 ofclosely woven fabric stretched tightly within a wire frame 3 togetherwith a top layer 4 of loosely woven fabric sewed to base piece 2 or towire frame 3. Coiled wire springs 5 are seated upon base 2 and tiedtoget-her in definitely spaced relation by cords 6, while the bottomloop 7 of each spring is screwed into or interlaced with the open meshesof the top layer 4. The said pieces or parts are assembled and built upat the bench to provide a unitary structure of predetermined size,preferably somewhat smaller at base 7 than wooden frame 8 to permit aseries of coiled suspension springs 9 to be stretched horizontallywithin the gap or space bordering three sides of the wooden frame. Theinner ends of springs 9 are hooked to wire frame 3 and the outer endsthereof are connected to the side loops 10 of a series of wire clips 11having their end portions bent at right angles and terminating in roundeyes 12. Clips 11 are therefore adapted to embrace the rectangular railsof the frame with the terminal eyes 12 resting against the top andbottom edges of the rails, thus permitting screws or nails 14. to beeasily driven vertically through each eye into the center part of therail. Each clip is fastened securely in place by two nails and the pullof suspension spring 9 is applied horizontally to the side loop 10,which is located relatively near one end of the clip, see Figs. 3 and 4.Having a side loop so positioned, the clip may be used in two Ways, thatis, loop 10 may be placed relatively near the bottom edge of the rail offrame 8, as in Fig. 3, or the clip may be inverted to place this loopnear the upper edge of the rail, as in Fig. 4, thereby establishingeither a high or low point connection for the spring seat or bottomwithin the wooden frame 8. The top of the seat may be placed in that wayin either a higher or lower plane relatively to the chair or couchframe, thus permitting the upholsterer to adapt the seat to chairs andcouches of different height 1 and the operation and kind and style. Theclips are nailed at spaced intervals to the rails and the built-upspring seat is then connected to the loop 10 by the suspension springs9.

The heaviest load on the seat is usually adjacent the rear of frame 8and therefore, I prefer to augment the spring tension for the seat atits rear. For that purpose I connect two suspension springs 9 and 9' tothe rear edge of flexible base-2 and the border wire 3 therein, seeFigs. 1 and 2, and employ wire clips 11' having two side loops 10'instead of only one loop. One spring 9 extends horizontally and thesecond spring 9 is stretched at an inclination of approximately 45 asshown in Fig. 2. The front as well as the rear of the seat may besupported in that way, or I may nail coiled wire hooks 15 to the frontrail 16 and connect the front border wire of flexible base 2 to thesehooks as shown in Fig. 2.

\Vhat I claim, is:

. 1. A resilient bottom for a chair or couch having a frame, comprisinga flexible base supporting a series of springs, suspension springs forsaid base and clips attaching said suspension springs to the frame ofthe chair or couch, the rear side of said base being suspended by twoseries of cooperating suspension springs angularly related to eachother, and attached to side loops of said clips arranged above eachother.

2. A resilient bottom for a chair or couch as described in claim 1, inwhich the front side of said base is supported by a number of springswith relatively little elasticity as compared with the elasticity of theother of said suspension springs.

In testimony whereof I aflix my signature.

. JACOB KRONHEIM.
